In turf applications, which spreader type tends to create more drift?

• A. Rotary spreaders
• B. Drop granular spreaders
• C. Both equally drift
• D. Neither drifts

Answer: (A)

Drift happens when wind carries applied material away from the target area after you spread it. Rotary spreaders fling granules outward from a spinning hopper, producing a broad, outward-reaching distribution pattern. That combination of a wide throw and higher exit velocity means more material is exposed to wind and can be carried off-target, especially at typical field heights. In contrast, drop granular spreaders release material almost straight down through a narrow opening, so most of the product lands near the target with minimal horizontal travel. Because of this focused, vertical application, drift is reduced with drop spreaders. So, in turf applications, the rotary spreader tends to create more drift. To minimize drift, use a drop spreader for precise applications and apply under favorable wind conditions, keeping the spreader close to the ground and properly calibrated.
